All work will be conducted by a qualified medical physicist (QMP). The QMP performs shielding design analysis report and shielding survey report reviews of radiotherapy vaults (primarily Linear Accelerator [LINAC] vaults) at the request of the contracting officer s representative (COR). The contractor reviews radiation shielding design analysis reports and shielding survey reports to ensure they meet criteria set forth in NCRP Report No. 151 and will result in radiation exposures that do not exceed the design goals in NCRP Report No. 151 and the radiation exposure limits set forth in Federal Regulations. The contractor will also provide training, if requested, to the NHPP Program Managers on technical reviews of shielding analysis and survey reports. The QMP must meet the following qualifications: A Qualified medical physicist is a person who is certified by the American Board of Radiology in Radiological Physics, Therapeutic Medical Physics, or Therapeutic Radiological Physics; American Board of Medical Physics in Medical Health Physics or Radiation Therapy; Canadian College of Physicists in Medicine, or American Board of Health Physics. The QMP will provide documentation he/she meets the required certification (must be current and active) for this contract.
